I might be picking up a 87 brat from MR. Mcbrat in the next week and I am looking in to doing a ej22 swap with this car. My main question I have is what is the big difference from doing a ej22 swap on a ea81 then a ea82? The reason I ask is that I can find tons of post for the swap on a ea82 but I can not find much info on a ea81 swap. OH one more thing.. I dont know if it matters but it has a 4 speed D/R tranny.

Thanks

so what is the necessary modification needed if using both EJ motor and tranny? does crossmember work? is the axle issue as easy as switching the front DOJ's? what is the EJ gear ratio? is it 3.9 too? I just scored a complete drive train from an impreza and was thinkin the whole AWD thing would be cool seeing how I rarely offroad. Thinkin of one of my t-coupes maybe cause one has possible bad engine, haven't determined problem yet though. It would probably make for a sleeper car for sure:brow: .

as i understand it, the tranny tunnel has the have the crap pounded out of it for the larger EJ tranny to squeeze in there. the impreza and legacy trannys are mostly 4.111, not the 3.90 in your tranny, but since you have the whole drivetrain you wont have to worry about trying to match diff to tranny. you'll need your drivshaft to be shortened because the legacy/impreza trannys are longer because of the AWD.
